Definitions

  • the invention relates to a storage container for holding a hot fluid having a temperature of at least 200 ° C comprising an outer shell, an inner shell and an intermediate thermal insulation layer according to the preamble of claim 1.
  • US 2011/017196 A1 discloses such a storage container.
  • the invention relates to the use of such a storage container for energy storage in solar thermal power plants and a use for retrofitting conventional storage containers.
  • Conventional storage containers for holding hot fluids e.g. liquid semiconductors or liquid salts usually have a cylindrically shaped container wall.
  • the container wall heats up until it assumes the temperature of the hot fluid stored in the storage container. Up to a temperature of 400 ° C, low-alloy C-steels can be used for the vessel wall. At higher temperatures, however, austenitic Cr-Ni steels must be used.
  • the container wall is usually surrounded on the outside by a thermal insulation. In the case where the fluid is e.g. exceeds a certain chloride content, according to the current state of the art because of the corrosion effect only expensive nickel-based materials such. 1.4876, 1.4958 and 1.4959 (INCOLOY® Alloy 800 H / HT).
  • the required thickness of the container wall and the desired temperature level of the fluid to be stored in these materials has a significant impact on the manufacturing cost of such a storage container.
  • There is a limit to an economically useful maximum storage volume since an increasing volume of the storage container and a higher temperature each require a thicker container wall thickness required to achieve the required strength. From a certain wall thickness, it is necessary to anneal the welds with considerable technical effort, whereby the manufacturing costs are further increased.
  • the storage container is provided with a thin-walled inner shell, which is mechanically supported by a temperature-resistant and load-bearing thermal insulation.
  • the thermal insulation is at the known design designed so that the temperature of the vessel wall does not exceed 400 ° C. It is therefore necessary in such a design, an additional external insulation.
  • the thermal expansion of the cylindrically shaped inner shell which occurs for example when filling with hot fluid, is made possible by elastic beads in this thin-walled shell. In order to compensate for the occurring radial and axial thermal expansion, in the prior art crossing points of beads, which are very expensive to manufacture, are incorporated into the thin-walled inner shell.
  • the inner shell is designed in the form of a standing on the point straight circular cone.
  • it is particularly advantageously possible to make the inner shell thin since a thermal load caused by the injection of hot fluid does not lead to a predominantly radial thermal expansion that impairs the strength of the storage container because of the peculiarity of the conical shape. Rather, it has been found that, due to the shape of the straight circular cone, the resultant of the expansion forces, which act upon heating, run essentially parallel to the lateral surface of the straight circular cone.
  • the inner shell therefore extends "vertically" upwards parallel to the conical surface or in the direction of the generators of the straight circular cone under thermal stress, ie the height of the circular cone increases slightly, but not the diameter of the circular cone at a certain height , The diameter at a certain height, which means heights below the initial height, rather remains constant.
  • the thermal expansion of the inner shell is approximately form-retaining due to the particular shape according to the invention.
  • the temperature of the fluid is preferably above 200 ° C, more preferably in the range of 400 ° C to 650 ° C, in particular in the range of 590 ° C to 610 ° C, more preferably around 600 ° C.
  • the inner shell may, for example, have a salt-tight and salt-resistant membrane, or a low-alloyed C-steel or an austenitic Cr-Ni steel or a nickel-based material or another suitable material.
  • the inner shell is floating on the thermal insulation layer, which in turn is preferably designed load-bearing, preferably also in the form of a standing on the tip straight circular cone.
  • the thermal insulation layer for example, mineral materials such. Calcium silicate stones or foam glass blocks or a combination of such or similar materials.
  • the thickness of the thermal insulation layer is such that the outer shell, whose almost entire outer surface can release heat to the outside, as a rule, regardless of the level of the storage tank, but at least after a certain time after a larger level change, approximately Ambient temperature has.
  • the outer shell can therefore be carried out with particular advantage in a concrete construction. Reinforced concrete is preferably used here.
  • the outer shell is formed load-bearing, preferably also in the form of a standing on the point straight circular cone or preferably as a load-absorbing polygon, which is particularly preferably provided inside with a lining, which is the shape of a standing on the top of a straight circular cone as an inwardly facing surface shape forms.
  • a lining which is the shape of a standing on the top of a straight circular cone as an inwardly facing surface shape forms.
  • clay is suitable as a material for said lining.
  • the floating inner shell Due to this particularly advantageous load distribution, it is possible for the floating inner shell to be very thin, e.g. only 2mm thick perform, which in particular in expensive materials, the efficiency of a storage container according to the invention can be increased again.
  • the concept of floating inner shell in the cone shape according to the invention which dispenses with complex mechanical connections to the outer shell, also allows for thin material thicknesses, since due to the shape-retaining properties, the inner shell can be provided with stiffeners that do not hinder the thermal expansion.
  • a storage container according to the invention is expediently equipped with a roof, which usually has a, preferably thermally insulated, suspended ceiling.
  • a mechanical interface between the inner shell and the thermal insulation layer is provided.
  • This mechanical separating layer additionally supports the concept of the floating inner shell (also called “floating shell”).
  • lean clay for use in the mechanical release layer is a suitable material.
  • beads are provided only along a few generators of the straight circular cone to compensate for variations in the thermal expansion of the material of the inner shell. It can also be compensated for fluctuations, which are e.g. caused by different subsidence of the thermal insulation layer.
  • the opening angle of the straight circular cone forming the inner shell is selected such that the surface of a predetermined nominal filling volume of the storage container is minimized.
  • an exactly form-retaining storage container was found.
  • both the material requirements for the storage container and especially for the inner shell, and the heat losses of the fluid over its surface are advantageously minimized.
  • the shape preservation is optimized in this embodiment. Thermal loads, e.g. by filling fluid, do not lead to deformation of the inner shell.
  • the optimization of the shape-retaining properties may be e.g. be approximated that the lateral surface of the right circular cone is minimized. This results theoretically in an optimal opening angle of about 70.5 °. In practice, however, opening angles in the range of 65 ° to 75 °, preferably in the range of 68 ° to 72 ° and particularly preferably 70 °, have proved particularly suitable for the present invention.
  • two types of storage of fluids with a lower and an upper temperature level can be distinguished, both of which make it possible to keep these temperature levels largely separate:
  • the present invention is basically suitable for both types of memories.
  • the inner shell is adapted to store a fluid having a higher chloride content.
  • a liquid salt with a higher chloride content than 0.1% as a fluid used.
  • it can be used advantageously and inexpensively salt, which was not treated accordingly in terms of its chlorine content.
  • so-called solar salt about 60% NaNO3 and 40% KNO3
  • heat carrier salt about 60% NaNO3 and 40% KNO3
  • the inner shell or at least the contact surface of the inner shell with the salt expediently comprises a suitable material, such as e.g. a belonging to the group of nickel-base materials already mentioned above material. Since such materials are expensive, the thin design of the inner shell according to the invention is of particular advantage here.
  • a storage container for storing solar energy converted in a solar thermal power plant in the form of a hot fluid, preferably a hot liquid salt having a temperature in the range of 500 ° C to 650 ° C, preferably 570 ° C to 610 ° C, particularly preferably 600 ° C, represents an advantageous development of the present invention.
  • Another advantageous embodiment of the invention provides for a use of a storage container according to one of claims 1 to 7 as an insert in a conventional, for example in the form of a cylinder formed storage container.
  • the resulting dead residual volume of the conventional storage container is suitably used with heat-insulating materials such as e.g. Clay, sand, wool, mineral wool or brick filled.
  • a further advantageous embodiment of the invention provides that a salt transfer pump is provided within the inner shell to reduce a non-usable salt volume. Preferably, this is centered, that is arranged along the central axis of the straight circular cone in the region of the tip of the cone within the inner shell. According to a further advantageous embodiment, the salt transfer pump is fixed in the radial direction by a slide bearing built into the tip of the cone.
  • the present invention can be further developed in that a drainage line is provided in the region of the tip of the cone, through which impurities settling in the fluid can be discharged.
  • the unusable tank volume can be advantageously permanently reduced.
  • the present invention has an improved design: on the inner surfaces of the inner shell of the storage tank baffles may be mounted, which reduce the movement of the stored fluid in the event of an earthquake.
  • a solid concrete foundation In general, such a storage container, as described in the present invention, a solid concrete foundation.
  • a foundation may be placed on this foundation e.g. annular wall (so-called “second containment”), the height of which takes up to about one third of the cone height.
  • the previously described concrete feet for supporting the cone can be mounted inside or outside of this wall.
  • the outer shell is designed as a steel construction.
  • the thermal insulation layer can be made thinner, for example, since the outer shell designed as a steel construction may be subjected to a higher temperature than a concrete construction.
  • a steel construction of low-alloy carbon steel of a temperature of max. 400 ° C without negatively affecting the properties of this steel construction in any way.
  • the outer shell is at least partially surrounded by an outer insulation in this embodiment. This applies to both the outer shell itself and how also on any existing supports that support the outer shell, for example on a foundation.
  • the steel construction is similar to the previously described concrete construction preferably designed load-bearing.
  • the outer shell has both concrete or Stahltbeton components and steel components.
  • the present invention provides a variety of savings in the creation of such a storage container, which is z.T. also additionally impact in less maintenance. It is thus proposed an economically very interesting solution.
